PhD: Topological spin textures and excitations in van der Waals magnets

Magnetic skyrmions, homochiral spin spirals and other exotic forms of magnetic textures are currently under intense scrutiny in non-centrosymmetric materials. The recent advent of 2D van der Waals magnets opens an exciting new playground for the search new classes of chiral magnetic objects. This PhD project is a collaboration with experimental and theory groups at LPS, Orsay, SPINTEC and Néel Institute, Grenoble. Using generalized Bloch theorem, the candidate will search for unconventional forms of the antisymmetry Dzyaloshinskii-Moriya exchange interaction and the related emergence of topological spin textures in van der Waals magnets with low crystal symmetry.
